Two-dimensional density fields of LCDM.10 models with particle density threshold ρ₀ = 10. Top panels: 2D density fields of thickness L = 8 h⁻¹ Mpc at z-coordinates 100,  200,  300. Bottom panels (from left to right): thickness L = 512,  128,  32 h⁻¹ Mpc. We show the central sections of 2D density fields of size 256 × 256 h⁻¹ Mpc. The colour scale is linear, and the code is identical in all panels.
